Abstract (en)

[origin: EP3621180A1] There is provided a cooling system (40; 40A to 40D) for cooling a stator (12; 12A) for an electric machine (10) and a method for producing such a cooling system. The cooling system (40; 40A to 40D) comprises at least two cooling channels (47; 470) for receiving a coolant (50), and at least one connector (45; 60) for connecting the at least two cooling channels (47) at one face of the stator (12; 12A), wherein each one of the at least two cooling channels (47; 470) is configured to serve both as supply unit and discharge unit.
